Biology, Bad Genes: A Relationship for Crime
Every hour of every day is the time it takes for two citizens to die due to violence. During the same time 250 citizens will need medical attention for an injury related to violence. With each passing hour the cost mounts, on average over a million dollars for each violent fatality and several tens of thousands for each non-fatal assault. These figures are enormous compared to other health issues of this century (Buckholtz, 2012).
There is little effort on the aims of scientist and criminal law that would have them working together and that is treading cautiously. Brain Imaging has come into light in the past decade or two that shows structural and functional deficiencies in the frontal and temporal lobes. These frontal and temporal lobes regulate aggression. Some say there is a gene some call the “warrior gene” which is aggressive. The actual name is MAOA. Some are using this as a defense when a person is being tried for a violent crime.
Also research of violent and aggressive psychopathic individuals have proven that several biological markers do exist and these are; lowered heart rate, abnormal EEG, multiple abnormalities in right temporal lobes and greater abnormalities in left temporal lobes.

Scientist have also discovered prefrontal damage encourages; risk taking, irresponsibility, rule-breaking, emotional and aggressive outburst, argumentative, violent criminal acts, loss of self-control, immaturity, lack of tact, inability to modify and inhibit behavior appropriately, poor social judgment and violence.
Our genetics is a set of building blocks that dictate among other things how our brains are built, function and get wired together. Every thought, emotion or

Biological Criminal Behavior

... Through-out history criminal intents have escalade from small crime to federal crimes seen in cases today. Research have proven genes influence the outcome of a behavior in a criminal behavior and the type of attach committed to his or her victim. This crimes are taught in the school of crime into five different steps to help during a crime investigation. One of these cases is Andrea Yates, who committed a horrific crime on her family. This paper will explain the changes in history of crime and the procedures done in a crime. The paper will also include the story of a criminal who committed the crime. Genetic evidence that confirms that biology does play an important part in explaining an offender’s criminality. Some believe that desire to commit crimes may be inherited and that criminal inclinations are genetically based. Research has been done extensively to discover evidence that would support this claim that has been made by intellectuals. Criminal deeds have always been a motivation due to the debate of nature and nurture. Studies have been done in regards to this debate that has resulted in a conclusion that both genes and environment do play apart in the criminality of a person. The research has stated that it is more often collaboration between genes and the atmosphere that predicts criminal behavior. Studies done on a family are the third type of instrument used to evaluate the relationship between genetics and environmental influences on criminal or antisocial...

Personal Reflection

...Many people tend to be uneducated about how a person becomes addicted to a drug. It is often assumed that abusers lack common sense, moral principles or willpower. Drug addiction is actually a very complex disease that requires much more than good intentions to overcome. The initial decision to consume drugs in any way is voluntary for most people. After that, changes in the brain occur over time and challenge a person’s self-control. So why do we harm our bodies and take drugs? The possibilities are endless. Many people feel that it is necessary to drink or experiment with drugs to satisfy a certain stereotype or to fit in at social gatherings. Others use drugs as a way to cope with daily stresses such as tension from school or work, relationship distress, or even physical illness. Drugs are also used as a way to compensate for feelings of guilt or low self-esteem. None of these reasons are “rightful” or “equitable”. I personally believe that here in the United States, drug use and abuse is a problem. Drug abuse and addiction have a much greater amount of negative consequences than they ever will have positive. These consequences don’t just affect us individually; they also affect our society as a whole. The total overall cost of substance abuse in the U.S. exceeds $600 billion annually. Family disintegration, loss of employment, failure in school, domestic violence and child abuse are all non-monetary implications of drug abuse. No single factor can predict whether a person...

Evaluation of Criminal Theory

...Evaluation of Criminal Theory The study relating to the causes of, and reasons for, crime has long been an interest to criminologist and psychologist. Since the mid 1800�s different aspects of the scientific community have explored the question of why people commit crime. This paper will discuss several theories that have developed over the years, how those theories have grown and changed and which theories seem to be the most prevalent today. The theories that will be discussed revolve around the biological and psychological study of crime, the strain and cultural deviance studies of crime and the social control aspects of crime. All of these studies and theories will be compared and examined to understand the standing of criminology today. The first study of why people commit crime revolved around the belief that criminal behavior resulted from a persons� abnormal psychology. These theories suggest that criminal behavior is caused by some underlying physical or mental condition. These conditions separate the societies criminals from the non- criminals (Adler et. al, 2007 p.116). The first people to study this rationale where called Positivist Criminologist and believed that; Human behavior is determined by forces beyond individual control and that is it possible to measure those forces�{They} view criminal behavior as stemming from biological, psychological and social factors. (Adler et. al, 2007 p.60) In the late 1870�s, Cesare Lombroso...

Why Do People Kill Violent Behavior?

...In today's society many people try to find ways to justify people's wrongdoings, some say “I was born this way” or that it is in their genes to be or think a certain way. Although most people in society believe that violent people are born with an aggressive nature, most violent people become aggressive due to recurring violent events in their life because they are exposed to violence repeatedly and become conditioned to committing violent behavior. Society today tries to make excuses for the things they have messed up in their life, people try to blame their genetics on how they do things, but they do not understand that the experience in their lives contorts their opinions and how they react to things, “In many cases serial killings, the behavior is influenced by past experiences and backgrounds…” (Pandey). People's minds are shifted whenever abuse and past experiences sway them. Flashback is a psychology term used to describe someone experiencing a traumatic event and an object or emotion felt during the event will trigger the feelings and events of that time. For an example, if you were in a traumatizing car crash, the loud of of something being crushed or metal being dropped will trigger and bring back all the emotions from the original event. Children who have been through...

Myths of a Racist Criminal Justice System

...being a drug dealer and addressing all of the concepts of what and constitute and define a drug dealer, and it does get a bad rap, but at the same times it is glorified through songs and movies. We will address the issue of whether being a criminal is an inherent trait or learned behavior, the average age group of most dealers and their family and social environments. I will only use data as it pertains to cocaine, whether it is powder or crack, heroin and methamphetamine since they are the preferred choice. What constitute criminal behavior Criminal behavior is a behavior in which the offender commits an offense that has been deemed as being unlawful act and punishable by the government and usually it is against individuals or property. Criminal behavior is seen as being prohibition or possession that constitutes a menace against the general public or society. In hope of confining and understanding criminal behavior researcher begin to study the brain of violent crime and compare their findings to the brain imaging “normal” individual. Through doing this they came up a new field of study called neurocriminology. Adrian Raine has studied the brain image of murders, violent criminals and psychopaths and from this research, he is convinced that there is a social and environmental cause to violent behavior. Although he is also convinced there exist a biology side of this type of behavior (npr.org, 2013). Believing that just as it is a biological reason for schizophrenia and anxiety...

Characteristics Of Serial Killers

...Looking into the minds of serial killers is a tricky task, a couple questions to start with are questions such as what is a Serial killer? According to the FBI’s version of the definition, a serial killer is conventionally defined as a person who murders three or more people in a period of over a month, with “cooling down” time between murders. “For a serial killer, the murders must be separate events, which are most often driven by a psychological thrill or pleasure. Serial killers often lack empathy and guilt, and most often become egocentric individuals; these characteristics classify certain serial killers as psychopaths.” (crime museum editors, 2017).

Epis' Paper on Positivism

...-“Strauss versus Brains and Genes or the postmodern vengeful return of positivism.” This essay first started as an answer to what I deemed very problematic, i.e. the disputation which I found in bad faith (un-authentic to use a philosophical term or an existentialist term), of the mediatic, dashing Harvard cognitivist/linguist, Steven Pinker, in his article “Neglected novelists, embattled English professors, tenure-less historians, and other struggling denizens of the Humanities, Science is not your Enemy—a plea for an intellectual truce,” (The New Republic--August 19). Then the counter-arguments against Steven Pinker’s conception of the “human animal” developed into an essay arguing that the New Positivism, not science, or technology per say, was the enemy of humanism and its avatars as such. The point is not to become a postmodern anti-scientific Luddite. Genomics are changing the world in ways we barely imagine yet and will re-define what it means to be human (a becoming already imagined by science fiction writers, social critics and critical thinkers such as the feminist Donna Haraway with her “Cyborg”). The point is also not to turn “anti-brainiac.” Without a brain we would become vegetative, a vegetal…, i.e. a purely “natural body,” a “zombie.” If we make use of this “computer” allegory which is an analog but not a homologue, and which is used ad nauseam used by psycho-biologists, without a hard-drive there is no software. But is this a reason to say that the software...

Superhero Awareness

...video games. Unfortunately, some people cannot find the line between reality and fiction and often blur the two, or disregard reality completely. There are many cases of people who choose to do bad because it is what they want to do and there are others who do this because of something that happened in their lives at a young age. There is really no way to know when the need starts or how it manifests itself in an individual. Doctors and scientists who are trying to figure out if criminality is psychological or biological, have had a long standing debate. Which path has the correct answer to this question or at least the most promising evidence and where does it all start? Although there are many good cases arguing for both there is no clear answer to this question. In the fictional realm of superheroes and supervillains, there are numerous reasons as to why the latter of the two chooses a life of crime. The psychological ramifications of nature versus nurture are an everpresent idea that shapes the hero versus villain dynamic as we know it. In the article “Does Cartoon Violence Beget Aggressive Behavior in Real Life? An Opposing View” by Fran Blumberg et.al, states that showing younger people violence in a way that can be considered to be funny, changes the way that they think about crime concluding that criminality starts at a younger age. For example, Krcmar and Hight (2007) found that “preschoolers who watched an action cartoon or super-hero image…were more likely to...

Inside the Mind of Giselle Esteban

...been accused of murdering Michelle Le, 26. Le went missing on May 27, 2011 and was found in a shallow grave in the Sunol-Pleasanton wilderness on September 17, 2011. Esteban was indicted on December 14, 2011 and entered a plea of not guilty. In November of 2011, Giselle gave birth to her 2nd child. Her trial date is set for September 17, 2012. (Kurhi, 2011). Using a bio-psychosocial approach, we are trying to understand why she thought, acted and felt the way that she did. One can consider, what was the biology of her mind, the psychology of her motivation, and the social aspect of her memories? Here we consider the possibilities of what causes a person to terminate another human’s life? Esteban 3 Giselle and Michelle were friends at Mt. Carmel high school in San Diego. Eventually, they relocated to the bay area. Giselle lived in an apartment in Union City. She was involved with a man named Scott Marasigan and their relationship resulted in a daughter who is now about five years old. Scott was awarded custody of their daughter and a restraining order, to prevent Giselle from having access to either Scott or their daughter, on May 24, 2011, just 3 days before Michelle disappeared.

...fficial Wikipedia app for Android: Faster speed, offline reading, and more. Last edited 3 days ago by an anonymous user Personality psychology Personality psychology is a branch of psychology that studies personality and its variation between individuals. Its areas of focus include: Construction of a coherent picture of the individual and his or her major psychological processes Investigation of individual psychological differences Investigation of human nature and psychological similarities between individuals "Personality" is a dynamic and organized set of characteristics possessed by a person that uniquely influences his or her cognitions, emotions, motivations, and behaviors in various situations. The word "personality" originates from the Latin persona, which means mask. In the theatre of the ancient Latin-speaking world, the mask was not used as a plot device to disguise the identity of a character, but instead was a convention employed to represent or typify that character. Personality also refers to the pattern of thoughts, feelings, social adjustments, and behaviors consistently exhibited over time that strongly influences one's expectations, self-perceptions, values, and attitudes. It also predicts human reactions to other people, problems, and stress.[1][2] There is still no universal consensus on the definition of "personality" in psychology. Gordon Allport (1937) described two major ways to study personality: the nomothetic and the idiographic. Nomothetic psychology...

Public Sociology

...C. Wright Mills' Sociological Imagination Works Cited Not Included In 1959, C. Wright Mills released a book entitled ‘The sociological Imagination’. It was in this book that he laid out a set of guidelines of how to carry out social analysis. But for a layman, what does the term ‘sociological imagination’ actually mean? In his own words, Mills claimed “it is the capacity to shift from one perspective to another…the capacity to range from the most impersonal and remote transformations to the most intimate features of the human self – and to see the relations between the two of them.” . Mills believed that being able to see the relationship between the ordinary lives of people and the wider social forces was the key to the sociological imagination. Fundamental to Mills’ theory is the idea of ‘public issues’ and ‘private troubles’. An individual’s troubles are personal when they occur because of the person’s character. Public issues, however, are a direct result of the problems within society, they affect people hugely but often the individual will assign the problem as their own personal downfall rather than as a societal problem. An ordinary man may get depressed about being unemployed and automatically accept it as his own personal trouble. He will be condemned as being ‘lazy’ or ‘work-shy’ and labelled simply as a ‘scrounger’. However, if there are thousands of other individuals also unemployed, Mills argues...

...Introduction In mass media today, there are numerous gaps between reality and the information that is presented. Seemingly every current issue, whether it’s political, social or otherwise, is reported through so many different outlets and with so many different facts that it’s hard to grasp what the reality is. The role of media in democracy is to represent every perspective and to provide well-researched and accurate information to create an educated and involved society. Media’s representations impact our society’s perception and shared reality. The way media represents a certain topic creates a public perception. Because of media framing, they can show us certain sides of an issue or shine a light on one perspective while effectively dimming the light on another. Because of this, we create perceptions based off of information that may not be whole. With these perceptions, we begin to construct a social reality. Once this reality is created, it is difficult to change it even if we find contradicting information. Because of these reasons, the way media represents information is crucial. The issue that will be discussed in this paper is that of gay marriage, stereotypes of homosexuals, and the scientific side of homosexuality. The way media has represented this topic over the past 30 years has varied immensely. We’ve come a long way over the past couple decades and homosexuality is now widely discussed in all forms of media including news, television, advertisements, movies...

8. Successful Leaders Have a Clear Sense of Purpose. What Is Your Statement of Purpose

...RICHARD DAWKINS-The Selfish Gene. Ebook v1.0. 'Who should read this book? Everyone interested in the universe and their place in it.' Jeffrey R. Baylis, Animal Behaviour Our genes made us. We animals exist for their preservation and are nothing more than their throwaway survival machines. The world of the selfish gene is one of savage competition, ruthless exploitation, and deceit. But what of the acts of apparent altruism found in nature-the bees who commit suicide when they sting to protect the hive, or the birds who risk their lives to warn the flock of an approaching hawk? Do they contravene the fundamental law of gene selfishness? By no means: Dawkins shows that the selfish gene is also the subtle gene. And he holds out the hope that our species-alone on earth-has the power to rebel against the designs of the selfish gene. This book is a call to arms. It is both manual and manifesto, and it grips like a thriller. The Selfish Gene, Richard Dawkins's brilliant first book and still his most famous, is an international bestseller in thirteen languages. For this new edition there are two major new chapters. 'learned, witty, and very well written...exhilaratingly good.' Sir Peter Medawar, Spectator Richard Dawkins is a Lecturer in Zoology at Oxford University and a Fellow of Mew College, and the author of The Blind Watchmaker.
